Abstract: Discharging a 10 kJoule/25 kV capacitor bank on a pair of coils in such a way, that the electric currents in the two coils have opposite directions, a cusp-shaped plasma (electron densities of about 10$^{17}$cm$^{-3}$, electron temperatur up to 200 eV) is produced. The maximum magnetic field was 75 kGauss at the line and point cusps, the half-period was 3.6 $\mu$sec. Due to this short half-period the plasma could be contained no longer than 2.5 $\mu$sec. With a crowbar system (time-constant 20 $\mu$sec) the containment of the plasma was strongly improved. Using streak-camera and spectroscopical methods, the spaceand time-dependence of the electron density and an estimate of the electron temperature is obtained.
